NASCAR Sprint Cup Series star Tony Stewart’s helmet is up for grabs, and one fan will take home the lid the Chevrolet driver uses during the Aug. 17 Cup race at Michigan International Speedway. No, Stewart won't be throwing the helmet. He'll likely just hand it to the winner.

Visit Mobil 1's Facebook page to check out the “Race to the Helmet” contest, where you can vote for the design Stewart will wear at MIS and enter for a chance to keep the helmet and attend the race.

Based on fan voting, the helmets will be narrowed down each week until only the winning design remains. The contest is open until July 25, and three helmet designs remain open for voting. Participants may cast one vote per day, and each vote will count as an entry for a chance to win a chance to not only keep the helmet but also attend the Pure Michigan 400 with a guest.

“For many drivers, our helmet is something we take a lot of pride in,” said Stewart. “I have a helmet collection of my own, so I’m helping give fans a chance to start their own collection. I know my fans have good taste and I can’t wait to see what design they pick.”

The winning design will be unveiled on the Facebook page on Mon., July 28, and the contest winner will be announced soon after.
